Chimney Inspection
Do I really need a chimney inspection every year in Danbury?
We hear this from Danbury homeowners all the time, especially when the fireplace seems fine. Long winters, heavy snowfall, and constant freeze-thaw cycles take a quiet toll on chimneys. A yearly inspection catches early cracks, draft problems, or hidden moisture before they become bigger issues.
During a recent visit in Hayestown, the chimney looked solid from the driveway. A camera scan revealed early flue cracking and a small moisture pocket that could have caused a leak by February. The homeowner had no idea anything was wrong.
Routine inspections keep your chimney safe, efficient, and ready for winter.
Chimney Repair
Why do chimneys in Danbury need repairs so often?
It’s the weather. Cold snaps, snow, and moisture strain masonry and mortar joints. Small cracks can let water in, and freeze-thaw cycles make them worse. Early repairs prevent smoke leaks, water damage, and heat loss.
One job on Mill Ridge stands out. A tiny crown crack allowed meltwater into the chimney chase, showing only as a faint ceiling stain. Quick crown repair and repointing solved the problem and protected the interior.
Fixing small issues early keeps Danbury homes safer and more winter-ready.
Chimney Cleaning
How often should I be cleaning my chimney in Danbury?
If you use your fireplace consistently through winter, an annual cleaning is your safest bet. Creosote builds faster in cold, damp climates like ours, and once it thickens, airflow drops and smoke has trouble moving the way it should. Cleaning keeps your fires burning warmer and your home smelling fresh.
I cleaned a chimney on Federal Road last season where the flue had narrowed from creosote buildup. The fireplace barely heated the room. After the cleaning, the draft returned instantly — you could feel the difference just walking past the hearth.
A clean chimney makes winter fires safer and more enjoyable.
Chimney Maintenance
Is seasonal chimney maintenance really worth it?
Absolutely. Cleaning and repairs handle immediate issues, but maintenance keeps the entire system healthy. It stops moisture wear, helps the chimney draft better, and prevents early deterioration — all things that matter in a climate as wet and cold as Danbury’s.
During a routine visit in Pembroke, I spotted early mortar softening around the crown. A quick seal kept moisture out and saved the homeowner from a full crown rebuild the next year. Little preventive steps make a big difference here.
Regular maintenance keeps your chimney strong through every storm.
Level 2 Chimney Inspection
When do I actually need a Level 2 chimney inspection?
A Level 2 inspection is for those “in-between” moments — when you’re buying or selling a home, upgrading appliances, or after a strong storm. It includes a video scan of the entire flue, giving a clear picture of what’s happening inside the chimney.
A homeowner in King Street called after noticing a faint smoke smell in a back bedroom. The Level 2 scan revealed a shifted tile deep in the flue, likely caused by winter moisture expansion. It was a quick fix because we caught it early.
Level 2 inspections give clarity whenever your chimney’s situation changes.
Chimney Crack Repair
Are small chimney cracks really something I should worry about?
In Danbury, yes — especially with how quickly water freezes and expands. Even tiny cracks allow moisture inside, and once that happens, deterioration speeds up. Small cracks can affect draft, increase creosote buildup, or eventually let water into the home.
I worked on a home in Great Plain where a “small crack” turned into a series of fractures behind the flue liner. The homeowner only noticed weaker airflow. A focused repair and seal made the system safe again and prevented a much larger rebuild.
Early crack repair keeps the chimney structure reliable through winter.
Chimney Leak Repair
Why is my chimney leaking even though it looks fine?
Chimney leaks are sneaky — most start in places you can’t see from the ground: the crown, cap, flashing, or small mortar gaps. Danbury’s wet winters make leaks common, especially during freeze-thaw cycles when moisture sneaks into tiny openings and expands.
One visit in the Main Street area uncovered a flashing gap no wider than a credit card. Meltwater had been slipping through every storm. A quick flashing repair and waterproofing seal fixed the issue and protected the home’s interior from further damage.
Hidden leaks are common but easy to fix once identified.
Chimney Cap Installation
Do I really need a chimney cap, or can I go without one?
In Danbury, a chimney cap is essential. It blocks rain, snow, and wildlife, protecting the flue from moisture — the leading cause of chimney wear. Without one, water gets into the system quickly — and moisture is the #1 reason chimneys deteriorate faster in this region.
I installed a cap for a family near Shelter Rock who had birds nesting in their chimney. After installation, the noise stopped, airflow improved, and the chimney stayed dry all winter.
A chimney cap is one of the simplest ways to protect your chimney year-round.

Honest Feedback from Our Clients
EXCELLENT Based on 356 reviews Posted on Daniel JacobTrustindex verifies that the original source of the review is Google. GMT Chimney Services did an outstanding job installing a new liner in my chimney. Their price was nearly half of what other companies quoted, and the work was excellent. My chimney wasn’t drafting correctly, which caused my water heater to break. After the liner was installed, the issue was completely resolved. Highly recommend for their fantastic work!Posted on Gary SandersonTrustindex verifies that the original source of the review is Google. Outstanding service with Joe he was very helpful and I would recommend gmt and JoePosted on Kevin HealyTrustindex verifies that the original source of the review is Google.

I would absolutely use this company again and felt he went above and beyond to assist usPosted on josh aTrustindex verifies that the original source of the review is Google. 3.5 stars Not the worst not the best experience.. the guys that came and did inspection were great and knowledgeable, the guys that came and did the liner were also great.. Juan that came to check out my fireplace and put on the caps was excellent.. the guys that came and did the pointing, and outside work did ok work but didnt communicate with us... never rang doorbells or gave us calls, not good communication.... this comapny expect you to be home almost at all times says they will work with you in times so, scheduled a day to come work and needed someone to be home wife took day off and they tried to tell us no one was home didn't even knock or ring door bell... just left tried to tell us no one was home and that they rang door bell and knocked.. we have cameras and ring door bell and wife took day off.. one week goes by no calls nothing gave us 30 min notice called abut 9a.m to show up around 930... again the workers were all pretty good but the communication between them the lady in the office and home owners should be better.. she Called and asked for payment job wasn't complete.. caps were not install.. Juan came out again was great did what he had to do and bill was paid.. I'd love to use them again for a cleaning because the work was ok and some of the guys doing the work. But they need to realize that people work for a living and cant be home at all times and some of the workers and the office need to be able to communicate with the home owners and possibly each other a bit better.. the pricing was average better then some others and work was overall ok.. if your someone that can be home often this company will be perfect for youPosted on MariaTrustindex verifies that the original source of the review is Google.
